7-diones as phosphonate analogues of acyclic nucleosides having nucleobases replaced with substituted 1,2,3-triazoles. All compounds containing P-C-C-triazole or P-C-C-CH2-triazole moieties exist in single conformations in which the diethoxyphosphoryl and substituted 1,2,3-triazolyl or substituted (1,2,3-triazolyl)methyl groups are oriented anti. All phosphonates were evaluated in vitro for activity
摘要:由ω-叠氮基烷基膦酸酯和乙炔二甲酸二甲酯合成了一系列2-(4,5-二甲氧基羰基-1H-1,2,3-三唑-1-基)烷基膦酸二乙酯,并将其进一步转化为相应的二酰胺,二酰肼,和5,6-二氢-1H- [1,2,3]三唑并[4,5-d]哒嗪-4,7-二酮作为无环核苷的膦酸酯类似物,其核碱基被取代的1,2,3-三唑取代。所有包含PCC-三唑或PCC-CH2-三唑部分的化合物都以单一构型存在,其中二乙氧基磷酰基和取代的1,2,3-三唑基或取代的(1,2,3-三唑基)甲基是反型的。在体外评估所有膦酸酯对多种DNA和RNA病毒的活性。没有一种化合物具有抗病毒活性。它们在100μM时没有抑制细胞生长的作用。
